This research aims to discover the quality of yoghurt added by rabbit skin gelatine of various concentrations. Qualities measured are protein content, fat content, acidity, pH, water holding capacity (WHC), syneresis, viscosity, and yoghurt texture. Materials used in this research are skim milk, rabbit skin gelatine, and yoghurt culture, which consisted of bacteria such as L. bulgaricus, S. thermophilus, and L. Acidophilus. The experiment is conducted using Completely Randomised Design, consisted of four treatments and five-time repetition. If there is an effect, the treatment later continued to Duncan's Multiple Range Test. Experimentation on texture is conducted through an organoleptic test with 25 panellists and later analysed with the Kruskal-Wallis Test. The treatments determined in this experiment are the effect on the addition of rabbit skin gelatin proportion of 0% (P0), 0.4% (P1), 0.6% (P2), and 0.8% (P3). The result of the Analysis of Variance (ANOVA) shows that the addition of gelatine has a significant difference (P<0.05) towards protein content, water holding capacity (WHC), and syneresis and no significant difference (P>0.05) towards the fat content, viscosity, pH, and yoghurt's acidity degree. The Kruskal-Wallis test result shows the significant difference (P>0.05) towards yoghurt's texture. This research concludes that the best yoghurt quality is obtained by the addition of 0.8% of rabbit skin gelatine.

<p>This experiment was conducted to determine the effect of zonation in closed house on ammonia levels and its impact on broiler chicken quality in the rainy season. The research was held in closed house, Faculty of Animal Husbandry and Agriculture, Diponegoro University. Three hundred and sixty broilers were divided into 24 groups (4 treatment, 6 placement groups of broiler): T1 (Zone 1, at the inlet position of the cage), T2 (Zone 2; ¼ of the length of the cage), T3 (Zone 3; ½ from the length of the cage ); T4 (Zone 4; ¾ of the length of the cage). During the study of ammonia levels, the temperature, humidity, and wind velocity inside and outside the cage were taken to obtain an overview of several factors that contribute to ammonia levels. The parameters observed were water holding capacity, pH, color, moisture content, fat content, and protein content. Water holding capacity and the color of the upper thigh meat increased significantly in the zone near the outlet (p &lt;0.05), but the water holding capacity and the color of the lower thighs and breast meat did not increase (p&gt; 0.05) in the zone near the outlet, but it has a darker meat color on the zone near the outlet. The pH did not show any significant difference (p&gt; 0.05) in the zone near the outlet. Water content followed by fat content of breast meat showed no significant difference (p&gt; 0.05) due to zoning. Breast protein content significantly increased (p &lt;0.05) in the zone near the outlet. It was concluded that placement in the zone near outlet had impact on the increase of water holding capacity, color, and protein content. Nevertheless, an increase in meat protein in the zone near the outlet is not followed by increased meat protein mass.</p>

Adlay is a nutritious grain that has the potential as an alternative food because it has a high protein and fat content of 14.10% and 7.90%, respectively. The use of Adlay as flour still has a weakness, namely the functional properties of Adlay flour such as low swelling power. One way to improve the characteristics of Adlay flour is by fermentation using Rhizopus oligosporus. The fermentation duration is the time that allows changes in the characteristics of the flour due to the fermentation. This study aims to determine the effect of differences in fermentation duration using Rhizopus oligosporus on the physical, chemical, and functional characteristics of Adlay flour produced from fermented Adlay seeds. This study used one factor, namely the lengths of fermentation for 0, 12, 24, 30, 36 and 48 hours. The analysis in this study included whiteness, yield, pH, water content, ash content, protein content, fat content, carbohydrate content, swelling power and solubility, oil holding capacity (OHC) and water holding capacity (WHC). The results have shown that the longer the fermentation duration the lower rate of whiteness, pH, yield, water content, fat content, and carbohydrate content will become, while some functional properties of Adlay flour become better with increasing values of ash content, protein content, swelling power, solubility, Oil Holding Capacity (OHC), and Water Holding Capacity (WHC).

in recent years, great attention has been paid to the quality of eaten meat and its products. There have been launched a lot of promotional campaigns aimed at providing opportunities for the consumption of traditional products. Based on the experiment, a significantly higher protein content was found in sausages produced by large producers (24.73 &plusmn; 1.98%). The fat content was significantly higher in traditional ham (16.25 &plusmn; 14.47%), compared with local ham (4.38&nbsp;&plusmn; 2.26%) and the mass (9.29 &plusmn; 5.25%). The samples of traditional and local ham had a significantly higher salt content (3.31 &plusmn; 0.72 and 2.90 &plusmn; 0.54%, respectively). No dye compounds were detected in any of the tested samples. There were no statistically significant differences in hydroxyproline and l‑glutamic acid content between traditional and conventional samples of meat products. Analysis of nitrate (V and III) showed a statistically significant difference in the average contents of these compounds. Significantly higher levels of nitrates were revealed only in traditional ham samples (12.60 &plusmn; 8.08 mg NaNO(V)/kg and 17.53 &plusmn; 27.91 mg NaNO(III)/kg of the product, respectively), wherein there was a large variation in the content of these compounds in the samples.

Mutton samples (m. longissimus thoracis et lumborum; LL) originating from 30 Istrian ewes were used to determine EZ drip loss (DL), thaw loss (TL), cooking loss (CL), and Warner-Bratzler shear force (WBSF) in relation to age at slaughter and different post mortem aging periods (1, 7, and 14 days). DL was measured according to the EZ method after storage periods of 24 and 48 h. Determination of TL, CL, and WBSF was performed for samples aged prior to freezing for 1, 7, and 14 days. A significantly lower TL (P<0.05) was observed in the mutton samples that aged for 1 day (7.76%) prior to freezing compared to the mutton samples that aged for 7 days (9.91%) and 14 days (9.32%) prior to freezing. The WBSF revealed significant differences between the aging periods (P<0.05), indicating that mutton aged 7 (33.92 N) and 14 (28.23 N) days showed greater tenderness than mutton with a shorter aging period (43.89 N). Considering that there was no significant difference between mutton aged for 7 and 14 days in water-holding capacity and shear force, there is no reasonable reason for aging mutton longer than 7 days. Therefore, further research into shorter aging periods, the sensory quality of mutton, and its acceptability by consumers is needed.

The objective of this work was to investigate the effect of addition of transglutaminase (TG-0.02%, w/w) and whey protein concentrate (WPC-0.03%, w/w), on quality of kombucha fermented milk product. Samples were prepared from pasteurized semi-skim milk (0.9%, w/w fat) and kombucha inoculum (10%, v/v). The pH values were measured during the fermentation of milk (lasted until reached 4.5). Syneresis, water holding capacity and the product texture (firmness and consistency,) were assessed after production. Rheological properties of kombucha fermented milk samples were measured during ten days of storage. The sample containing TG had the lowest syneresis (21 ml), the highest water holding capacity (62%) and the highest textural characteristics (firmness - 23.99g, consistency - 626.54gs) after production. The addition of WPC to milk improved the rheological properties, while the addition of TG improved it even to a significantly greater extent after the production and during 10 days of the storage.

Quality of plain set yoghurt was investigated by varying levels of ultrafiltration concentration of cow skim milk (1-without ultrafiltration, 1.5 and 2 folds) and inoculum (2, 2.5 and 3%) of yoghurt culture (Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus 1:1). Titratable acidity development and pH reduction were significantly faster during incubation of yoghurt with increasing ultrafiltration concentration level and inoculum level. Increased ultrafiltration concentration level decreased spontaneous whey syneresis, but increased water holding capacity and firmness of the product significantly. Body & texture and overall acceptability scores were significantly better in yoghurts prepared from 1.5 fold concentrated milk irrespective of the inoculum level studied. Inoculum level did not show any significant effect on the quality of yoghurt, but higher inoculum level decreased the incubation period significantly. Optimized product was obtained with 1.5 fold concentrated skim milk standardized to 3.3% fat and incubated with 2% inoculum level in about five and a half hour of incubation. Optimized product had 13.60±0.02% total solids, 3.31±0.01% fat, 5.27±0.04% protein, 4.20±0.03% lactose and 0.82±0.02% ash. Whey syneresis, water holding capacity and firmness in optimized product were nil, 63.49% and 1.89 N, respectively. Thus, high quality plain yoghurt could be prepared by employing ultrafiltration, without addition of stabilizers, which is otherwise widely used commercially for the manufacture of yoghurt to control its wheying off and body.
